Huma reg question for impact

[Arnie]

So I bought a Huma regulator for my impact. However, I don’t know whether I bought the high pressure reg or low pressure reg...it came with 12 Belleville washers so I’m thinking it’s a high pressure one...but the orientation is what differs from high pressure to low pressure? How can I tell which one I bought? Does one have thicker washers?

How should I orient the washers just to be safe?

I just recently installed a Huma Gen 2 regulator. There are different numbers of washers on the Gen 2 when comparing High and low pressure. It took a minute going over the installation information online. I think there are different washer counts for different pressure. The Huma installation webpage is the reference I used. Hope you get it figured out.
